- ladite jambe est munie à son extrémité inférieure d'un coulisseau constitué par un bloc en matériau organique de synthèse emboîté en bout de cette extrémité et maintenu fixé à la jambe par des moyens appropriés, ce coulisseau étant conformé pou r pouvoir chevaucher la nervure du socle avec possibilité de pivoter sur la nervure autour dudit axe et de coulisser le long de la nervure, et- Said leg is provided at its lower end with a slider constituted by a block of synthetic organic material fitted at the end of this end and kept fixed to the leg by appropriate means, this slider being shaped for being able to straddle the rib of the base with the possibility of pivoting on the rib around said axis and sliding along the rib, and
- un dispositif de liaison est établi entre la jambe et le socle pour maintenir le coulisseau sur la nervure.- A connecting device is established between the leg and the base to maintain the slide on the rib.
On décrira ci-après un exemple de réalisation d'un cric conforme à l'invention définie ci-dessus cet exemple présentant de plus d'autres caractéristiques qui font partie de l'invention, isolément ou en combinaisons. Dans cette réalisation, le dispositif de liaison comporte un arbre qui traverse la jambe et/ou le coulisseau parallèlement audit axe et qui est attaché au socle de façon à pouvoir pivoter autour dudit axe.An exemplary embodiment of a jack in accordance with the invention defined above will be described below, this example also having other characteristics which form part of the invention, alone or in combinations. In this embodiment, the connection device comprises a shaft which crosses the leg and / or the slide parallel to said axis and which is attached to the base so as to be able to pivot around said axis.
La description fera référence aux figures du dessin joint sur lequel : - la figure 1 est une vue générale du cric dans la position d'introduction sous la voiture ;The description will refer to the figures in the attached drawing in which: - Figure 1 is a general view of the jack in the insertion position under the car;

- la figure 6 est une vue générale du coulisseau, etFIG. 6 is a general view of the slide, and
- la figure 7 est une vue générale du cric pivoté en position de fin de course d'élévation.- Figure 7 is a general view of the jack pivoted in the end-of-travel elevation position.
Le cric représenté sur les figures est du type en Y. Ce cric comporte essentiellement, de façon connue en soi, un mécanisme élévateur constitué d'une jambe d'appui 1 sur laquelle est articulée autour d'un axe 2 une jambe elévatrice 3, des moyens étant prévus pour que cette jambe elévatrice puisse pivoter autour dudit axe sous la commande d'une manivelle 4 (figure 1 ).The jack shown in the figures is of the Y type. This jack essentially comprises, in a manner known per se, an elevating mechanism consisting of a support leg 1 on which an elevating leg 3 is articulated around an axis 2, means being provided so that this lifting leg can pivot around said axis under the control of a crank 4 (FIG. 1).
La jambe d'appui 1 prend appui au sol par l'intermédiaire d'un socle 5 et la jambe elévatrice 3 est munie d'un accessoire 6 qui lui permet d'accoster par en dessous un véhicule schématisé par le profil latéral 7 de sa caisse (fig. 1 ).The support leg 1 is supported on the ground by means of a base 5 and the lifting leg 3 is provided with an accessory 6 which allows it to dock from below a vehicle shown diagrammatically by the lateral profile 7 of its body (fig. 1).
Selon l'invention, ce socle est constitué par une plaque métallique 5a qui a été déformée localement, par exemple en son milieu, pour constituer un tunnel longitudinal 5b à section droite sensiblement en forme de U, ce tunnel constituant l'axe de pivotement X'X. En variante le tunnel pourrait être formé par un cylindre rapporté sur la plaque, mais cette réalisation serait moins avantageuse.According to the invention, this base is constituted by a metal plate 5a which has been locally deformed, for example in the middle, to constitute a longitudinal tunnel 5b with a straight section substantially in the shape of a U, this tunnel constituting the pivot axis X 'X. As a variant, the tunnel could be formed by a cylinder attached to the plate, but this embodiment would be less advantageous.
La jambe d'appui 1 comporte deux parois parallèles l a, l b, généralement métalliques, qui déterminent entre elles à l'extrémité inférieure de la jambe un espace dans lequel est emboîté un bloc 8 réalisé dans un matériau organique de synthèse ayant un bon coefficient de glissement et une bonne résistance mécanique, par exemple un bloc de polyacétal. Ce bloc est retenu emboîté par des pattes 14 formées aux extrémités des parois la, l b et repliées contre le bloc après encastrement du bloc. Ces pattes sont représentées avant repli sur la figure 2 et après repli sur les figures 3 et 5. On peut en variante utiliser d'autres moyens de fixation, par exemple un collage.The support leg 1 has two parallel walls 1a, 1b, generally metallic, which determine between them at the lower end of the leg a space in which is fitted a block 8 made of an organic synthetic material having a good coefficient of slip and good mechanical resistance, for example a polyacetal block. This block is retained fitted by lugs 14 formed at the ends of the walls 1a, 1b and folded against the block after the block has been fitted. These tabs are shown before folding in FIG. 2 and after folding in FIGS. 3 and 5. One can alternatively use other means of fixing, for example a bonding.
Le bloc est conformé avec une sous-face 8e creusée en arrondi (figure 5) pour chevaucher le tunnel 5b de façon à pouvoir pivoter d'avant en arrière sur le sommet du tunnel et de pouvoir coulisser le long du tunnel.The block is shaped with an 8th underside hollowed out in a rounded manner (FIG. 5) to overlap the tunnel 5b so as to be able to pivot back and forth on the top of the tunnel and to be able to slide along the tunnel.
Le bloc présente deux talons 8a, 8d qui limitent dans un sens et dans l'autre sens la course de pivotement du bloc (et donc de la jambe) par butée contre la plaque 5a du socle (fig.). Les deux positions de fin de course de pivotement de la jambe sur le socle correspondent respectivement à la position d'introduction de la jambe sous la voiture (figure 1 ) et à la position de levage maximal où la jambe est verticale (figure 7).The block has two heels 8a, 8d which limit in one direction and in the other direction the pivoting stroke of the block (and therefore of the leg) by abutment against the plate 5a of the base (fig.). The two end-of-travel positions for pivoting the leg on the base correspond respectively to the position for inserting the leg under the car (Figure 1) and the maximum lifting position where the leg is vertical (Figure 7).
La course de coulissement du bloc (et donc de la jambe) sur le socle est délimitée dans les deux sens par les pattes 5c, 5d formées dans la plaque de socle aux extrémités du tunnel 5b. La jambe est liée au socle par un dispositif de liaison qui comprend deux arbres parallèles 9, 10, l'un des arbres 9 traversant des perçages 1 1 formés dans les parois l a, l b de la jambe et/ou traversant le bloc, l'autre arbre 10 traversant le tunnel 5b et ces deux arbres étant reliés entre eux par des plaquettes 12 ou tout moyen équivalent. L'arbre 9 peut ne traverser que les flancs métalliques l a, l b de la jambe (au dessus du bloc) ou ne traverser que le bloc, mais de préférence comme dans le cas représenté, cet arbre traverse et la jambe et le bloc, ce dernier servant de palier à l'arbre.The sliding stroke of the block (and therefore of the leg) on the base is delimited in both directions by the tabs 5c, 5d formed in the base plate at the ends of the tunnel 5b. The leg is linked to the base by a connecting device which comprises two parallel shafts 9, 10, one of the shafts 9 passing through holes 1 1 formed in the walls 1a, 1b of the leg and / or passing through the block, the another shaft 10 passing through the tunnel 5b and these two shafts being interconnected by plates 12 or any equivalent means. The shaft 9 may only cross the metal flanks 1a, 1b of the leg (above the block) or only pass through the block, but preferably as in the case shown, this shaft crosses both the leg and the block, this the latter serving as a bearing for the tree.
L'arbre 9 est continu comme dans le cas représenté ou est discontinu. Dans ce cas il est constitué par exemple de deux arbres situés respectivement à droite et à gauche du bloc et qui présentent chacune une extrémité ancrée dans le bloc.The shaft 9 is continuous as in the case shown or is discontinuous. In this case it consists for example of two shafts located respectively to the right and to the left of the block and which each have one end anchored in the block.
De même, l'arbre 10 est continu ou est constitué par deux pièces qui seraient enfoncées respectivement à l'une ou l 'autre des deux extrémités du tunnel.Likewise, the shaft 10 is continuous or consists of two parts which would be inserted respectively at one or the other of the two ends of the tunnel.
L'arbre 9 et l'arbre 10 ont des sections droites quelconques. Dans le cas représenté, l'arbre 9 est cylindrique et l'arbre 10 a en section droite la forme d'un secteur circulaire, mais ces formes n'ont été choisies qu'à titre d'exemples. L'arbre 9 porte des ressorts 13 qui repoussent la jambe vers une position située au milieu de sa course de translation.The shaft 9 and the shaft 10 have any cross sections. In the case shown, the shaft 9 is cylindrical and the shaft 10 has in cross section the shape of a circular sector, but these shapes have been chosen only by way of examples. The shaft 9 carries springs 13 which push the leg towards a position located in the middle of its travel.
De préférence, le bloc 8 est prolongé latéralement, au-delà des parois la, lb de la jambe 1, par des parties 8b, 8c qui constituent des capots cachant les ressorts 13. Dans cette réalisation, selon un aspect important de l'invention, un grand nombre de fonctions sont réalisées par le bloc 8 en matière organique de synthèse, venu de moulage et éventuellement usiné. On voit notamment sur la figure 6 qui est une vue du bloc seul qui celui-ci a la forme d'une selle qui présente : - une sous-face 8e en arrondi rentrant conformée pour pivoter sur la nervure du socle.Preferably, the block 8 is extended laterally, beyond the walls 1a, 1b of the leg 1, by parts 8b, 8c which constitute covers hiding the springs 13. In this embodiment, according to an important aspect of the invention , a large number of functions are performed by the block 8 in synthetic organic material, molded and possibly machined. We see in particular in Figure 6 which is a view of the single block which it has the shape of a saddle which has: - an 8e underside in rounded reentrant shaped to pivot on the rib of the base.
- des côtés longitudinaux 8a, 8d plats inclinés en remontant vers l'extérieur pour constituer les deux talons qui limitent la course de pivotement de la jambe sur le socle ; - deux encoches 8f pour recevoir les pattes 14 repliées des flancs métalliques de la jambe ;- Longitudinal sides 8a, 8d inclined dishes going up towards the outside to form the two heels which limit the pivoting stroke of the leg on the base; - two notches 8f for receiving the folded legs 14 of the metal sides of the leg;
- deux alésages coaxiau 8g, 8h débouchant à l'extérieur pour recevoir les extrémités des ressorts 13 et laisser passer l'arbre 9 ;- two coaxial bores 8g, 8h opening to the outside to receive the ends of the springs 13 and letting the shaft 9 pass;
- un alésage central 8i qui relie les alésages latéraux et qui sert de palier à l'arbre 9 ;- A central bore 8i which connects the lateral bores and which serves as a bearing for the shaft 9;
- facultativement deux prolongements 8b, 8c qui servent de capots pour cacher et protéger les ressorts 13. Dans ce cas des feuillures 8j, 8k sont ménagées entre la partie centrale du bloc et les capots pour recevoir les extrémités des flancs métalliques de la jambe. L'invention n'est limitée ni à son application à un cric du type- Optionally two extensions 8b, 8c which serve as covers to hide and protect the springs 13. In this case rebates 8j, 8k are provided between the central part of the block and the covers to receive the ends of the metal sides of the leg. The invention is not limited nor to its application to a jack of the type
Y ni à cet exemple de réalisation, l'homme de métier pouvant, s'il le désire, n'utiliser qu'une partie des moyens décrits ou remplacer des moyens décrits par d'autres moyens fonctionnellement équivalents. Y nor to this embodiment, the skilled person can, if he wishes, use only part of the means described or replace means described by other functionally equivalent means.
